Scientists have been using complicated, hypothetical particles to explain the Big Bang, but this theory posits that a simpler ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

A new paper presents a method for distinguishing between different sources of nanohertz gravitational waves. Pulsars may be ...

For decades, astronomers have listened to the cosmos through pulsars — rapidly spinning neutron stars that emit perfectly ...

Might the universe we can observe be just half the tale, with a mirror universe moving in reverse through time filling out the narrative? A new and intriguing idea from scientists at the Perimeter ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the universe. Gravity was traditionally defined by Isaac Newton’s Law of ...

We'll cut right to the chase: This video of Stanford Professor Andrei Linde finding out about yesterday's big discovery of "smoking gun" evidence of cosmic inflation (the "first tremors of the big ...

Update 12:05 p.m. — The team at the Harvard-Smithsonian Center for Astrophysics has announced they've found "The First Direct Evidence of Cosmic Inflation." The scientists say that after three years ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array ...

"If the model holds true, it could mark a new chapter in the way we think about the birth of the universe." A radical new theory regarding the origin of the universe suggests that gravitational waves, ...
